But not just any workout will do the trick, it's strength training that's a must.

"So how does lifting weights increase your strength? Well by performing movements with resistance your body and muscles will get sour but your muscles will eventually grow and adapt creating strength."

It's something which Deana Markham says she found at Crossfit.

"If I went to a gym I would go on a treadmill and I didn't push myself very hard. This is more weights then I have ever done before and I can see just working around the house or in the yard I can do more then I have ever been able to do," she said.
